This, however, did not fix the noise that is present in the video I had previously uploaded.

I went for a ride with the tech and the shop foreperson, where we, fortunately, were able to replicate the noise. He seems confident that it's wind noise, and he will attempt to locate the cause on Monday. Fingers crossed.
I just had what sounds like the same noise start ocurring on Tuesday, 9100 miles. Sounds almost like a Kerker muffler on a motorcycle from a distance. You can hear it coming up if you listen carefully around 52+ but most prominent 65+. The pitch changes ever so slightly with speed. Before that there was a whirring kind of noise at aprx same speeds that they did not acknowlege a problem which I just knew was going to get worse. May or may not be relted. Brought it in for service and the same old thing, seems they don't want to acknowledge problems. Can't duplicate, wind noise, others do it, etc. That might be the case if it was always ocurring but when it just started happening, its obviously a problem that needs fixing. Funny when my non-tech wife heard it start happening at the same time I did and asked what the noise was and they can't acknowledge a problem. I picked up the vehicle and on my way from service it was quite evident so had to turn back around and bring it back to them. Test drive with shop foreperson and he acknowledged the problem thank goodness. When you open your wallet and fork out +$90k cash, obviously not what you are expecting. They asked me what I would like them to do about it... uh, identify the problem and fix it. Seems they want me to identify the problem for them. I have to bring it back to them on Tuesday. It started ocurring just after my service for H264 and other updates. Noise sounds mechanical in nature to me and may not be related to wind. I asked them they can setup mics in the frunk to help locate. Guess we'll see what happens. I asked about the same thing, oil, motor, what kind of drive train is up front, etc.

I'll keep you updated if/when I Iearn anything.

I don‘t know if the noise is the same but I have an open issue since I bought my car with Jaguar. They already replaced the front drive unit and one side of the front drive shaft and it did not solve the problem. The dealer really has no clue what the root cause is and last November they wrote a letter to Jaguar. I received no further information so far. The noise starts at ~90kmh and is noticeable till a speed of ~125kmh but only during light acceleration. The noise isn‘t changing a lot depending on speed, it is just noticeable in the mentioned speed region under light acceleration. And no, it’s no wind noice, no street surface tire sound or usual whirring of the e-motor. The last idea of the garage was that it is not a mechanical cause and more a synchronising problem between front and rear drive unit but that is just a guess of them and no officially statement. They said I can drive the car and should not worry. H264 has been applied in the meantime but no changes to the issue.

Got the car back from the dealership. They said they bolted down something or other. Regardless, it did not fix the problem. I contacted Jaguar of North America and they opened a ticket number. I also scheduled a service appointment at a different dealership. They (Rusnak of Pasadena) will take the car on the 17th and be in touch with Jaguar directly to try to solve the mystery noise. I appreciate the feedback from others. If there are three of us experiencing this problem, I'm certain there are more as well. Please let us know if anyone finds a fix!

Best,
Adam

Mine makes a similar sounding noise at speeds over 40 mph when the air conditioning is not running. I've done some tests that seem to confirm that it has something to do with the air conditioning. Mine sounds like wind noise. It seems to happen when the cabin is being heated, but not when it is being cooled. I haven't had mine looked at by service yet. Hopefully one of us will get to the bottom of it and restore a quieter serenity for all of us.

I'll tell you Adam, I'm having the exact same noise and conditions. The trouble came on abruptly one night on mine and my wifes drive home. My wife asked at the same time I started hearing it, "what's that noise". Had to be persistent with the dealer but they recognized the problem and are working on it. They stated its the front EDT (Electronic Drive Train). Had parts coming in from California then they needed other parts that are coming in from the UK. I believe the main parts are in from Cal but still waiting on parts from UK. My wonderful iPace I can't live without has now been at the dealer for over 11 days and counting collecting dust. (I'm special, they put me in a RAV4) Hate the thought of anyone doing such a major job on my baby but what can you do. Hope and pray its this EDT and not one of those ongoing things until they identify the problem.

I wonder if we'll start hearing more about this EDT...

PS The service advisor and tech were going to give the vehicle back to me as is with the usual "they all do it we're trying to help" customer intelligence insulting comment. I had to return and drive it with the shop lead and direct him to where the sound was coming from asking what was between the two motors that could be causing a sound like this which I believe helped them identify the issue with the EDT.

Well, sheep sheet. When I took mine in for the H264 update (a whole other story), I got it back and I noticed the noise. I looked and they tech had forgotten to put the plastic screws in the plastic engine cover, so I thought BAM. That must be it. Mine sounds like wind noise, and even happens at different speeds depending on wind direction and speed. Went back to the dealer, picked up some of the screws and thought all was right with the world.

Nope. I even took off the plastic cover completely and same noise.

For those of you in this boat, mine only happens at speed (65+ with wind sheer, 75+ without). It stops as soon as you slow down. I would have sworn it was flapping plastic, but know you all have me wondering. WHat does yours sound like?

We've contacted the dealership so we'll see. Bought the car in January, the problem arose with less than 1k mikes.

If anyone else has a ticket open with JLNA please DM me the number so I can provide it to Jaguar when I take my car in.

Sometimes a cigar is just a cigar. And sometimes what sounds like flapping plastic IS just flapping plastic. At least it was in my case. Service test drove it, heard it, fixed it within three hours on a walk in apppointment. Just throwing it out there.

Props to Sacramento Jag, the customer service was top notch.

There have been occasions when the front plastic covers (frunk) are removed for the hood cable / latch fix, the front internal air duct above the grill can be incorrectly re-fitted.

An owner had mentioned this on one of the I-Pace forums, with whistles and resonant vibrations (humming) at higher speeds.

This happened to my vehicle too. When I inspected my air duct, I could feel and see that the lower edge of the rear ducting was partially obstructing the air passage with a 1/8" gap between the two surfaces.

The techs immediately took the car inside and refitted it correctly. I am unable to report what the sound effect would have been
